- B. [5marks] Assume that the arrival rate of demand to the current line is 26.875 units/hr, and there are no losses on any workstation. Calculate the utilization of each workstation on this line. Indicate Which Station is the bottleneck. Write the answer here(do not use percentage): Utilization of W/S 1 [1 marks]: Utilization of W/S 2 [1 marks]: Utilization of W/S 3 [1 marks]: Utilization of W/S 4 [1 marks]: The bottleneck station is [1 marks]: Explain this answer - Optional : - C. [10 marks] The average production of the current line has been 37.10 parts / hr with an average WIP level of 250 parts. The New line has an average production of 89.10 parts/hr with an average WIP level of 250 parts. Calculate the TH of each line based on the practical worst case performance. Write the answer here: THpwc of current line [4 marks ]= parts/hr. Write the answer here: THpwc of new line [4 marks ]= part/hr. Which line is performing efficiently? Choose an answer [2 marks]: Explain your answer here - Optional : Explain your answer - optional : Explain this answer - Optional : B. [5 marks] If the management would like to achieve a throughput equal to 80% of the line capacity, what should be the level of work-in-process on the line assuming best case performance? Write the answer here: WIP = parts. Explain this answer - Optional: A product requires four steps of processing on a 4-station production line. The relevant data for the line (Current Line) are given in the table below. A new line has been added with the same 4 operations to process the same product, but that line (New Line) uses a more advanced technology. Data is also shown. Answer the following question: - A. i) [6 marks] Calculate the capacity of each line? Write the answer here: Capacity of current line [ 3 marks]: parts/hr. Write the answer here: Capacity of new line [3 marks]: Use your textbook (Factory Physics) to answer the following question. Compare and contrast a balanced production line with an unbalanced production line, focusing on the flow of work and potential inefficiencies that might arise 11) [4 marks] Calculate the Critical WIP of each line? Write the answer here: Critical WIP of current line [2 marks]: parts. Write the answer here: Critical WIP of new line [ 2 marks]: parts. Explain this answer - Optional : Explain this answer - Optional : iii) [5marks] Comment on the potential differences in the Critical WIP levels between the old and the new production lines. What factors might contribute to these differences? \} - B. [5marks] Assume that the arrival rate of demand to the current line is 26.875 units/hr, and there are no losses on any workstation. Calculate the utilization of each workstation on this line. Indicate Which Station is the bottleneck. C. [5 marks] If the management is planning to achieve a throughput equal to 80% of the line capacity, what should be the level of work-in-process on the line assuming practical worst case performance? Write the answer here: WIP = parts. Explain this answer - Optional : D. [10 marks] Repeat parts B and C if the management would like to achieve a throughput equal to 85% of the line capacity. Write the answer here: [ 4 marks] WIP in best case performance = parts. Write the answer here: [4 marks] WIP in practical worst case performance = parts. Comment on the difference in the values of WIP levels from parts B and C to this part D [2 marks] : Indicate the following statement is true or false: The throughput of a line can exceed the bottleneck rate. a. True b. False and processing times of 30 minutes - Workstation 3 has 2 machine with average processing times of 6 minutes pe job - Workstation 5 has 6 parallel machines with average processing times of 9 minutes per job - Workstation 3 has 3 parallel machines with average processing times of 6 minutes per job A. [10 marks] Calculate the number of work in process units expected at each station. How can we benefit from this information in managing the production line? Write the answer here: WIP at workstation 1: parts. WIP at workstation 2: E. [5 marks] If two types of parts arrive to the line. The first type arrives at the rate of 9 units per hour and it needs processing on the first and third stations only. The second type arrives at the rate of 7 units per hour and it requires processing on all workstations. Assuming no defects or availability issues in the system, calculate the utilization of each station. Which station would be the bottleneck in that case? Write the answer here: Utilization of workstation 1: [1 marks] : parts/hr. Write the answer here: Utilization of workstation 2: [1 marks] : parts/hr. Write the answer here: Utilization of workstation 3: [ 1 marks] : parts/hr. Write the answer here: Utilization of workstation 4: [ 1 marks] : parts/hr.
